Figure 7. (A) Schematic diagram of the mechanism of SEI and CEI formation. This figure is quoted with permission from Goodenough et al.^[81]. (B) Schematic of how LiF-rich SEI prevents the growth of dendrites. This figure is quoted with permission from Choudhury et al.^[82]. (C) The schematic shows that when heated, the fluoropolymer, CYTOP, gradually breaks down to release pure F₂ gas. This gas then reacts with lithium metal or Li_xSi, resulting in a uniform and dense coating of LiF. This figure is quoted with permission from Zhao et al.^[84]. (D) Long-term cycling stabilities of anode at a current rate of 0.2 A g^-1 in 1m NaClO₄ electrolyte in PC without and with 2 vol.% of FEC additive. This figure is quoted with permission from Wen et al.^[88]. (E) Coulombic efficiency of Li||Cu battery at a current density of 0.10 mA cm^-2. This figure is quoted with permission from Zhang et al.^[86]. (F) Discharge capacities of the Li/LCO cells cycled at 1.0 C (1 C = 274 mA g^-1).
